The man behind Tukatech Mr. Ram Sareen is a well known liar and a thief. Of course Tukatech and Optitex are almost the same, they used to be business partners but now tukatech stole optitex software and sells it.
you can read about it in their web page http://www.optitex.com

all tukatech does is steal products and sell it with their name on it!
they did it to HP they did it to optitex and they are probably about to get an ugly fight in court...
